\paragraph{Data Encoding}
When interacting with a \gls{uicc}, either to request or to store data, the command payload is typically structured using \gls{asn1} encoded in the \gls{ber}-\gls{tlv} format. \gls{asn1} is a formal language used to define data structures in a way that is independent of machine-specific encoding. It is a mature and widely adopted technology, particularly within the field of telecommunications, and is standardized by the ITU-T~\cite{oss-asn1}.
\gls{asn1} supports a variety of encoding rules. One of the most commonly used in the context of smart cards and mobile communications is the \gls{ber}. In \gls{ber}, all data is encoded as a sequence of \gls{tlv} elements. The \emph{Tag} identifies the type of data, the \emph{Length} specifies the number of bytes used for the value, and the \emph{Value} contains the actual data payload.

\section{eSIM on SIM}
% - most popular option of integrating esims is directly soldering them onto the cricuit board of a smartphone
% - since the soldered esim is near identical to the SIMs normally distributed as physical SIMs -> esims can also be distributed as physical esims
% - Come in formfactors 2FF, 3FF, and 4FF to the best of our knowledge
% - most of the esims on sims we could find are manufactured by kigen, estcompeace, Giesecke+Devrient
